About this item

The black demon mask is obtained as a possible reward from master Treasure Trails. It is purely cosmetic and gives no bonuses. This item can be stored in the treasure chest of a costume room, provided that the master clue interface is opened before attempting to store the item. This requires a mahogany treasure chest.
